Subject: [LTP] [PATCH v2 1/2] mem: disable KSM smart scan for ksm tests
Date: Fri, 1 Dec 2023 13:09:29 -0800 [thread overview]
Message-ID: <20231201210930.2651725-2-shr@devkernel.io> (raw)
In-Reply-To: <20231201210930.2651725-1-shr@devkernel.io>
This disables the "smart scan" KSM feature to make sure that the volatile
count remains at 0.
Signed-off-by: Stefan Roesch <shr@devkernel.io>
Reported-by: kernel test robot <oliver.sang@intel.com>
Closes: https://lore.kernel.org/oe-lkp/202311161132.13d8ce5a-oliver.sang@intel.com
